Given
Slant height of the cone =50cm
Curved surface area of the cone = 2200cm^2
Solution
Let the radius of the base of the cone be r cm
Therefore,
πrl =2200cm^2
22/7×r×50=2200
2200×7/22×50= 14cm
Total surface area of cone = πr(r+1)
22/7×14×(14+50)
22/7×14×64 = 2186 cm^2
Therefore Volume of cone is 2186cm^2
